Abstract
A bstract We compute the mixed QCD⊗QED corrections to the production of on-shell Z bosons at the LHC at a fully-exclusive level. We also include the factorised NLO QCD correction to Z boson production and NLO QED correction to Z boson decay into two leptons. We make use of an abelianised version of the nested soft-collinear subtraction formalism to perform this computation. We study the phenomenological impact of the mixed QCD⊗QED corrections for a number of observables relevant for LHC phenomenology.
